Clinical analysis of continuous blood purification in children with severe adenovirus preumonia / 中国小儿急救医学

ABSTRACT

Objective:To discuss the role of continuous blood purification (CBP) therapy in children with severe adenovirus pneumonia.Methods:A total of 114 children with severe adenovirus pneumonia admitted to the Department of PICU at Children′s Hospital of Hunan Province from June 2018 to July 2019 were selected as the research objects.According to whether treated with CBP, they were divided into CBP group and control group.The following indicators during the process of treatment were compared between two groups, including respiratory mechanics indicators[respiratory index(PaO 2/FiO 2), dynamic lung compliance(Cdyn)]; hemodynamic indicators(heart rate and mean arterial pressure); changes in levels of inflammatory factors interleukin(IL)-6, IL-10, tumor necrosis factor(TNF)-α and the prognosis 28 days after admission. Results:The respiratory mechanics index, serum IL-6 and TNF-α levels of two groups after treatment were significantly lower than those before treatment, and the serum IL-10 level was significantly higher than that of this group before treatment.There were statistical differences in the CBP group before and after treatment, while there was no statistical difference in control group.In the CBP group, the serum IL-6 and TNF-α levels after treatment were significantly lower than those of the control group( P<0.05), and the serum IL-10 level was significantly higher than that of the control group( P<0.05). The 28-day mortality rate of patients in CBP group was 8.6%(3/35), which was significantly lower than 13.9%(11/79) of control group ( P<0.05). Conclusion:CBP could improve the main respiratory mechanical indexes of adenovirus pneumonia and decrease the level of inflammatory cytokines.
